Impressive WebDriver performance with HtmlUnit

A WebDriver user has recently posted interesting execution times for his test suite in HtmlUnit’s mailing list depending on the driven browser.

Here are his results for his 600 tests:

  • 2 hours: Sauce Labs
  • 40 minutes: Chrome
  • 10 minutes: HTMLUnit
  • 4 minutes: HTMLUnit + surefire plugin parallel execution

The complete email can be read here.

Of course this doesn’t mean at all that the HtmlUnitDriver is always faster than the “real” browsers. There are many cases where HtmlUnit is too slow, no discussion. Additionally more information would be interesting here to correctly interpret the execution times like the results when driving Firefox and the kind of browser simulated with HtmlUnit. Nevertheless such results are always encouraging for HtmlUnit’s developer.
